PENCIL.

SEEGIFICATION forming part of Letters Patent No. 717,884, dated January6,1903.

Application filed August 21,1902. Serialllo. 120,470. (No model.)

I'o all whom, it may concern,.-

Beit known that LALERED FORNANDER, a subject of the King of Sweden andNorway, and a resident of New York, in the county and State of New York,have invented certain new and useful Improvements in Pencils, of whichthe following is a specification.

My invention has reference to lead-pencils of that type in which onelong piece of loose lead is adjustably provided Within the pencil; andit is the special object of this invention to provide a pencil which isoperated Very quickly.

Heretofore the push piece or mechanism in mechanical pencils foroperating the lead or leads has been usually arranged at the top of thepencil. In my novel pencil the push mechanism is located near the frontend,where the pencil-point comes out. The mechanism is adapted to beoperated by one of the fingers when hand and pencil are in position forwriting. The pencil-point will come out during the period of operatingthe mechanism. After the pencil-point has come out the desired lengththen the mechanism is released, fixing thereby the point firmly in thedesired position. Having inished the Writing, the mechanism is operatedagain, whereby the lead slides back into the pencil, protecting thepencil-point while carrying the pencil in the pocket.

The invention isillustrated in the accompanying drawings, in which-Figure l represents a pencil in longitudinal section. Fig. 2 is a frontelevation of another modification, showing the lower part in section.Fig. 3 illustrates in section the lower portion of Fig. l on an enlargedscale. Fig. 4 shows in section the lower portion of Fig. 2 on anenlarged'scale. Fig. 5 is a side view of the spring and lead-guidingclamp device of Fig. l. Fig. 6 is afront view of same. Fig. v7 is afront View of the spring in Fig. 5. Fig. 8 is atop View of thelead-guiding clamp device. Fig. 9 illustrates in detail the spring`shown in Figs. 2 and 4, and Fig. 10 is a front view of same.

Similar letters of reference denote like parts in all the gures.

In the drawings, a. represents the receiver and receptacle for the leadb, which is loose therein, as is shown in Fig. l. The opening c in thereceptacle for the lead bar is conveniently large for permitting of afree movement of same. The receptacle for the loose lead is preferablyclosed at the top as is shown in Fig. l. The lower portion of thereceptacle is gradually tapering down toward the lead point, resemblingthus a common sharpened lead-pencil. Right near the tapering portionthe'mechanism is located. The lead is held in position by a lead guidingand clamping device d, which is not secured to the wall of the shell.(See Figs. l and 3.) The clamp extends into a broadened portion d',which is provided with an opening in the center, through which the leadpasses. The portion CZ' acts as the lead guiding and catching device andmay be of any suitable shape. lt may be circular in shape-for instance,like the lead guiding and catching device shown in Fig. 8. All that isnecessary is that the portion ci is broad enough to permit of making ahole through. The portion d of the clamp d extends through the wall a2of the shell and is almost rectangularly bent u pward, forming a smalltongue d2. A spring f is secured to the wall a2 of the shell,.bent, asis shown in Fig. 5, and ending within the bent portion of the tonguecl2. The clamp holds same in position.

Assuming now that the pencil is empty and Ya lead is to be inserted,thenthe tongue d2 is pressed downward until the broadened portion dstands at right angles to the center line of the pencil, when theopening therein will present its full Width, thereby permitting the leadto be easily inserted. N ow the lead is completely hidden in the channelc of the pencil. If the pencil shall be used, then all that is necessaryis to place the hand and ypencil in a writing position and press downthe tongue d2, thereby letting the lead pass out. After the desiredlength of the lead-point is out, then the mechanism is released and thebroad portion of the clamp moves out of the horizontal position, wherebythe somewhat sloping surface of the opening will permanently grasp thelead on two opposite sides of same. The pressure exerted while writingtends to hold the lead bar tighter in position.

Figs. 2 and 4: illustrate a modification in IOO which a spring g ofgreater length is ernployed, which is practically completely Within theshell. When in the position shown in Fig. 3, then the lead bar is tightand Writing can be done. If desired to let the lead bar go in or out,then the top portion g' of the spring is pressed in, so as to be in theposition shown in Fig. 4. In this instance the broadened portion d ofthe spring will be at right angles to the longitudinal center line ofthe pencil, permitting the lead bar to move in or out.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A pencil comprising a loose lead bar, a lead-barreceptacle, a channel therein extending below where the pencil-pointcornes out into a larger space, a spring secured near the point of thepencil looped at the top then bent under an acute angle and extendinginto a broadened portion having an opening therein which engages thelead and adapted to release the latter upon pressing it on its loweroutside portion.

2. In a pencil provided with a loose leadbar a spring looped at the topand bent under an acute angle broadened out there and having an openingin the broadened portion.

3. In a pencil With a loose adjustable lead bar, a spring-catch for thelead bar located near the front end Where the pencil-point comes outformed of a looped spring-top portion, a slightly acute angularly bentlower portion broadened out and an eyelet in the latter adapted toengage and release the lead.
